JOHN E.TENCATE, OF PITTSBURG, PENNSYLVANIA.

IMPROVEMENT lN SHEET-STEEL BELLS.

Specification forming part of Letters Patent No. 122,679, dated January 9, 1872.

To all whom it may concern:

Be it known that I, JOHN E. TENOATE, of

Pittsburg, in the county Of Allegheny and State of Pennsylvania, have invented a new and useful Article of Manufacture, viz.: a sleigh-bell constructed of one piece of sheet cast-steel; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to theaccompanying drawing andto the letters Of reference marked thereon.

The nature of my invention consists'in providing a newarticle of manufacture, t0 Wit: A spherical sleigh-bell, constructed of a single piece of sheet cast-steel, cut so as to form a hollow sphere, the walls of which are of uniform thickness, and provided with suitable openings for producing the necessary vibrations, whereby the desired notes or sounds are obtained from the bell.

To enable others skilled in the art to make and use my new article of manufacture, I will proceed to describe more fully its construction.

In the accompanying drawing which forms part of my specification, Figure l is a face view or plan Of the sheet of steel prior to bending into the form shown in Fig. 2, which represents the sleigh-bell.

In constructing my new article of manufacture, suitable patterns are made for each size of bell; these patterns are laid on the sheet of cast-steel, which is marked by a slate-pencil; the several pieces are then cut Out, as shown in Fig. 2., The part marked A will form the upper half of theliOllOW sphere, and the partsB and C the lower half Of the sphere. The part A is provided With an opening, e, for the tang D used for securing the bell to its strap. The parts A, B, and C are bent into the desired form by means of suitable dies, the part A being formed intoy a half sphere, then the partB being formed into a quarter of a sphere, and then bent with relation to the part A so that the two parts A and B will form three-fourths of the sphere. The ball for making the sound is then placed in the partially-formed sphere, and the part C bent so as to form the Whole sphere, as shown in Fig. 2. The hollow sphere is then tempered to the desired hardness. Even thickness of the walls and the metal used (cast-steel) will give the bell a sweet musical sound.

What I claim is- A spherical sleigh-bell, constructed of One piece of sheet cast-steel, substantially in the manner hereinbefore described.
